SPECIFICATION forming part of Letters Patent No. 392,586, dated. November 13. 1888. Application tiled February 17, 18S?. Serial No. 227.948. (No model.)

To @ZZ whom, it may concern.'

Be it known that I, PAscHAL GRoGnRY Gils- ;PIAN, la citizen of the United States, residing at Ph1ladelphia, in the county of Philadelph1a and State of Pennsylvania, have invented a new and useful Improvement in Adj nstable Frames for Holding Printing Mediums or F1lins, of which the following is a specification.

My invention relates to an improvement in adjustable frames for holding printing mediums or films; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is a top plan View ofa frame embodying my improvements. Fig. 2 is a transverse vertical section of the same, taken on the line a: x of Fig. l. Fig. 3 is a horizontal sectional view taken on the line y y of Fig. 2. Fig. 4 is a transverse sectional View taken on the line e z of Fig. I. Fig. 5 is a detached perspective view of the bedbar. Figg is a similar view of the verticallyadj ustable bar to which the hlm-frame is hinged. Fig. 7 is a detail view of one of the clampingyokes.

The object of my invention is to provide a vertically and laterally adjustable frame to hold a printing medium-such as a flexible printingtilm-now in use for artistic and dec orative purposes, and for printing and the preparation and finishing of drawings, and printing and copying surfaces.

A represents a base-frame,whicl1 is circular in shape, and has one side flattened to form a straight edge, B. In the center of the frame is made a rectangular opening, 0. rlhe bar which is formed on the straight edge of the base-frame is provided on its inner side with a metallic plate or bar, D. In the three remaining sides of the opening C are made grooves E, in which are inserted bars F, the outer sides of which are V-shaped in crosssection.

G represents a movable frame or table, which is square in shape and is adapted to fit in the opening C of the base-frame. This table G is composed of a pair of boards, H,which are secured on opposite sides of a rectangular metallic frame, I. The said frame comprises a vertical face-bar, K, which is arranged opposite the bar or plate I), side bars, L and M,

which are attached to the ends of the face-bar and project therefrom, and a cross-bar, N, which connects the said side bars, L and M near their outer ends. rIhe side bar M is provided with transverse slots M near its ends, and through the said transverse slots extend set-screws O, one of which enters one end of the cross-bar N, and the other of which enters an offset, K, that extends from the inner side of the face -plate K. The said side bars L and M have grooves formed in their outer edges adapted to receive the trackbars F, which project beyond the sides of the opening C, and thereby the said frame is adapted to slide laterally in the said opening. Brace-rods P connect the crossbar N and the face-plate K. By providing the side bar M with the slots and the set-screws to secure it to the bar N and the faceplate, the said side bar M is adapted to be adjusted outwardly from time to time when it becomes necessary to do so in order to take up wear. Studs R project from opposite sides of the bars L and M, and enter corresponding recesses which are made on the inner opposing sides of the boards H, and screws S are passed through the said boards at their `corners and also through the bars L and M in order to firmly clamp the said boards to the movable frame. On the outer side of the straight edge of the base-board A, at the center thereof, issecured a countersunk metallic plate, T. A thumbscrew, U, is swiveled to the center of the said plate and extends through an opening made in the straight edge of the base-board, and the inner end of the thumb-screw passes through and. engages a threaded opening which is made in the faceplate K of the movable frame. A coiled extensile spring, V, is placed on the threaded portion of the thumb-screw and bears between the faceplate of the frame and the metallic plate D on the inner side of the straight edge. Guide-rods NV project inwardly from the said plate D and enter openings which are made in the face-plate of the movable frame, and coiled extensile springs X are placed on the said guide-rods and bear between the face-plate of the frame and the plate D.

From the foregoing it will be readily understood that the function of the springs V and X is to force the movable frame laterally from the straight edge of the base-board A. By

IOO

turning the thumb-screw U the frame may be moved laterally toward or from the straight edge.

The block, lithographie stone, or other printing surface or drawing or design upon which transfers are to be made from the printingilm, is adapted to be secured upon the frame or table G, and is therefore movable with the said frame or table.

Y represents a bed-bar which is made of metal, and is provided at its extremities with depending offsets or shoulders forming feet Z, which are adapted to rest upon the upper side of the base-board A,so as to support the bedbar ata suitable distance above the base-board. The edges of the bed-bar are straight, and are parallel with each other, and in the said bedbar, and extending nearly throughout the entire length thcreof,is a longitudinal slot, A, which is arranged parallel with the edges of the bar.

B represents a pair of clamping-yokes, each of which is made substantially in the form of the letter U, and is provided with a clampingscrew, C. The function of these clampingyokes is to secure the bed-bar on the upper side of the base-board, and either parallel with one edge of the table or frame C, or at any suitable angle with relation thereto.

D represents a vertically-adj ustable frame, which comprises a bar, E', provided at its extremities with upwardly-projecting standards F and threaded shanks G, which depend lfrom the lower sides of the said standards. These shanks are adapted to extend through the slot A in the bed-bar,and adjusting thumbnuts H are screwed onto the threaded shanks G and bear against the upper and lower sides of the bed-bar. By turning the said thumbnuts it willl be readily understood that the frame D may be adjusted vertically with relation to the bed-bar.

I represents bearing screws which pass through threaded aligned openings which are made in the standards F, parallel with the .bar E. These bearing-screws have their inner ends pointed, and are provided at their outer ends with milled heads, and on the said screws are adjusting thumb-nuts L', which arc adapted to bear against the standards F', so as to secure the adjusting-screws against displacement.

N represents a rectangular rocking frame, comprising a pair of parallel arms, O', and a cross-bar, P', which connects the said arms near one end. rllhe ends of the arms project slightly beyond the cross-bar, and are provided on their outer sides with conical recesses adapted to receive the pointed inner ends of the bearing-screws, and thereby the rocking lframe is pivoted or hinged upon the verticallymovable frame D.

By reason of the slot A in the bed-bar the frame D may be moved longitudinally on the said bar, so as to move the rocking-frame N laterally with relation to the table or frame G.

R represents a rectangular frame, which is made of metal and is adapted for the attachment of the printing-nlm. The side bars of the said frame are hollowed throughout their length, and are adapted to receive the arms O of the rocking frame N, and thereby the said frame R is adjustable on the rocking frame toward or from the bed-bar Y. Set-screws S work in threaded openings in the side bars of the frame R,and are adapted to clamp the latter at any desired adjustment on the rocking frame. By making the rocking frame, which carries the film-frame, vertically adjustable, as before described, blocks or printing-surfaces of varying thicknesses may be placed under the printing-film, and thelatter maintained in a perfectly horizontal position, with its printingsurface nearly in contact with the surface of the block. By means of the adjustingscrew U the frame or table G may be moved through any desired distance, and its motion may be regulated with great nicety and exactness.

The printingsurface of thc printing-film may be stippled, ruled, or cross-hatched with straight or curved lines, according to the width desired.

The operation of my invention is as follows: The printing-film is attached to the frame B with its printing-face downward toward the drawing, design, or printing-surface to be operated upon, and when the face of the printing-film has been inked the rocking frame is turned down so as to bring the printing-face of the film nearly in contact with the surface of the drawing block or stone, and the lines or stipples are transferred by means of a stylus applied to the back of the printing-film, after which the rocking frame is turned so as to remove thc printing-film from the surface of the block, stone, or drawing, and the printing-face of the film is then reinked. If close lines or stipples are desired upon the drawing or printing block or stone, the frame or table G is adj usted by means of the screw U to such an extent that the lines printed the second time will be between those printed the rst time upon the drawing or printing block; but if the lines are to be heavy the block or table G is so adj usted that the lines printed the second time will partly cover or will bein contact with the lines printed first, so that these first lines will be increased in thickness, and in this manncr lines of any desired thickness can be produced. In order to cross-hatch upon the drawing or printing block or stone after the lines of the printing-film have been transferred thereon, the bed-frame will be removed from. the base-boardA by releasing the clamping-yoke, and the bed-bar will be secured again upon the base-board by means of the clamping-yokes in a position at a suitable angle with relation to its former position, as indicated in dotted lines in Fig. 1, and thereby when the rocking frame is again turned down, so as to bring the printing-face of the film in contact with the drawing or printing block, the lines on the said lm will be arranged at an angle with relation to the lines formerly printed on the drawing or block, as will be very readily understood.

IOO

By thus providing the bedbar with the clamping-yokes, to attach the bar to the bed-board at any desired point, I avoid shifting the block or drawing on the frame or table G after it has once been secured thereon, and thus greatly facilitate the operation of finishing or shading the drawing, as it sometimes is extremely difiicult to restore the block or drawing to the exact position which it formerly occupied on the board or table G after it has once been moved thereupon.

Having thus described my invention, I claiml. The combination of the base-board, the bed-bar to which the frame to carry the printingiilm is attached, and the clamping devices to secure the bed-bar to the base-board at any desired point, substantially as described.

2. The combination of the bed-bar having the slot A', the frame D', having the clampingstuds working in the said slot, and thereby adapted to adjust the frame D on the bedbar, and the frame to carry the printing-film pivotally connected to the frame D', substantially as described.

3. llie combination of the rocking frame N', having the parallel horizontal bars O', and the film-frame It', secured to said bars O' and detachable therefrom, substantially as specified.

4. The combination of the rocking frame N' and the film-frame R', secured thereto and adj ustable thereon, substantially as described.

5. The combination of the base-board having the opening Cand the track or guide bars F in the sides thereof with the table or block G, having the frame engaging the said guidebars, one side of the said frame being laterally adj ustablc to take up wear, substantially as described.

6. The base-board having a rectangular opening, (l, and formed with guides or ways, combined with the sliding table G, working in the guides or ways in the walls of the opening C, as set forth.

7. In combination with the base-board A, having the opening C, provided with the guides or ways, the sliding table G, movable in the guides or Ways of the said opening, the pins IV, the springs X, the screw U, and the lm-holding frame, as set forth.

8. In combination with the base-board A, having the opening C, the sliding table or block G, movable in the opening C, said table or block having one of its sides laterally adjustable, as set forth.

9. The combination of the base-board, the rocking frame N', hinged or pivoted thereto and having the arms O', and the film-frame R', having the longitudinal openings in its sides to receive the said arms, for the purpose set forth, substantially as described.

10. The combination of the base-board, the rocking frame N', hinged or pivoted thereto, the iilm-frame, and the set-screws S', securing the film-frame adjustably to the rocking frame, substantially as described;

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
